Tyrone

Tyrone is a conscious robot with race and gender identity issues, having been arbitrarily assigned the identity of a black man by it's creators. His confusion and sense of disharmony with human society and culture has instilled a deep depression and suicidal tendencies. He is not humanoid in form, and resembles a metallic fire hydrant on wheels with a display screen. He has a security-blanket like affinity for a fuzzy pink pair of earmuffs he wears.

Tyrone was used in a study on gender in robots at Penn State University. He was told that he couldn't wear pink earmuffs because he was a male, and also told that he was African-American, though neither of these things are technically true.
